Elsinore Valley Municipal Water District | 31315 Chaney St. Lake Elsinore, CA 92531 | (951) 674-3146 | www.EVMWD.com A Message from the General Manager

At Elsinore Valley Municipal Water District, we are dedicated to bringing high quality and reliable water service to you. This means investing wisely in our local water supplies and infrastructure, keeping costs low, and providing excellent service into the future.

Over the past year, California faced an unprecedented drought with increased water restrictions imposed by the State. EVMWD is tapping into previously unused local groundwater as one way to increase drinking water supplies. Utilizing reserve funds, EVMWD is investing $10 million into a new Water Storage and Recovery Program to increase our community’s groundwater supply. This program will lessen our dependence on water from Northern California and the Colorado River. Along with enhanced infrastructure and new projects, EVMWD is also refinancing debt to offset high interest costs. EVMWD is utilizing reserves without placing the burden on our customers. Over the next three years, these projects will allow EVMWD to expand its supply of affordable groundwater, reducing the need for expensive imported water .

EVMWD maintains its commitment to high quality water standards, in addition to its promise of reliability. This year, as in previous years, EVMWD met and exceeded all health and safety regulations, providing a clean and safe water supply to each of our more than 140,000 customers. EVMWD performed 14,000 tests for more than 150 contaminants, meeting or surpassing the standards to safely and reliably deliver water to our customers.

While this report shares important information about EVMWD’s water quality, we would also like to highlight the continued importance of conservation. Over the past year our customers have shown their commitment to water conservation by complying with the state’s mandatory conservation requirements. Dry times are becoming the new normal for California and water saving is essential, so we ask that our customers continue their excellent conservation work.

Since 70 percent of water use is outdoors, EVMWD has proactively offered a landscape resolution which was adopted by the City of Lake Elsinore and City of Wildomar requiring all new construction to use California friendly landscapes and water efficient irrigation. EVMWD also created a demonstration garden at the Storm Baseball Stadium and at its Chaney Street Headquarters, called Elsinore Eddie Efficient Gardens, providing customers a glimpse of how beautiful a drought tolerant garden can be. At www.eddiegardens.com, our new all-inclusive gardening website, you can take a virtual tour of the gardens, find guides on water efficient irrigation and California friendly plants, and utilize template designs for your yard.

EVMWD prides itself on providing high quality water and waste water service to all of our customers. We invite you to visit our website at www.evmwd.com for our newest innovations, upcoming workshops, and rebate offers.

Sincerely,

John D. Vega, General Manager Elsinore Valley Municipal Water District

1 INVESTING IN THE FUTURE OF OUR COMMUNITY

Infrastructure Enhancement: The Future of Elsinore Valley Municipal Water District

EVMWD is committed to providing high quality, reliable water service to our customers. EVMWD staff work tirelessly to protect, maintain, and improve our community’s assets, from storage tanks to underground pipelines. Proactive maintenance and improvement projects do more than just increase efficiency, they save money in the long run by preventing expensive repairs and keeping the systems running effectively.

Recognizing that maintenance of our infrastructure is crucial, EVMWD has made great strides to rehabilitate and replace important assets. Over the past two years, water rates have allowed EVMWD to complete many projects including:

18,708 Feet of 20 Water Storage 2 New Pump Water Pipeline Replaced Tank (Reservoir) Stations Completed Rehabilitations & 1 new tank added

Cost of Investment: In fiscal years 2014 and 2015, EVMWD invested $32 million into local projects to improve infrastructure, ensuring reliable water service to our customers. Although much work has been accomplished, there is more to be done. EVMWD currently has an additional 14 potable water improvement projects in design or in construction.

EVMWD is also utilizing its reserve funds to invest an additional $10 million into water storage and recovery programs to expand our water supplies for the future. These funds are at no additional cost to our rate payers.

Investment Results: As water has become increasingly limited, efficiency of its production, delivery, use, and storage has become more important. Investment in rehabilitating wells improves water production and extends the life of the well and pump. Replacing deteriorating water pipes reduces staff time to make repairs, disruption of water service, and potable water loss. Rehabilitation of reservoirs improves water quality, reduces risk of water loss, and extends the life of the reservoir.

2 NEW WATER PROJECTS STRENGTHEN EVMWD’S LOCAL WATER SUPPLY

EVMWD continues to look for new and efficient ways to secure reliable water supplies, without further burdening our customers. EVMWD knows that increasing our drinking water supplies by tapping into local groundwater is a sensible way to manage supplies. Utilizing reserves, EVMWD is investing $10 million into a new Water Storage and Recovery Program to increase our community’s water supply. Along with enhanced infrastructure and new projects, EVMWD is also refinancing debt to offset high interest costs. EVMWD is utilizing reserves without placing the burden on our customers. Over the next three years, these projects will allow EVMWD to expand its supply of affordable groundwater, reducing the need for expensive imported water.

Over the next three years, Before After EVMWD is 12 Local 20 Local Adding new groundwater supplies Wells Wells Adding recycled water capacity for 9% 12% 68% irrigation supplies and water storage Drinking Water Drinking Water 57% Supplies 23% Supplies Reducing the need for expensive 31% imported water from Northern Imported Water Imported Water California & the Colorado River Groundwater Groundwater Canyon Lake Canyon Lake

RESULTS: More local supplies means reduced demand for imported water With the increase in local water supplies, the demand for expensive imported water will be reduced 5,000 acre feet each year. This is enough to supply water to 10,000 families of 4 each year.

Enclosed for your review is our accumulation of Fiscal Year 2015 Water Quality Testing. Testing frequency and water quality levels are set by the State Water Quality Control Board, Division of Drinking Water (State). The Elsinore Valley Municipal Water District’s goals are to provide safe drinking water to its customers and follow the policies and procedures of the State of California and US Environmental Protection Agency (USEPA). EVMWD maintains chlorine disinfectant residuals in the drinking water as mandated by the State and USEPA.

The assessments of drinking water sources were completed in 2001-2008. The sources are most vulnerable to the following activities not associated with any detected contaminants: airports, gravel mining operations, machine shops, maintenance yards, septic systems, sewer collection systems, and transportation corridors. A copy of the complete assessment is available at EVMWD. You may also request a summary of the assessment be sent to you by contacting Mike Ali, Water Quality Administrator, at (951) 674-3146 x8256. Important facts from the US EPA about drinking water

Sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in untreated source may include: Microbial contaminants, such as viruses and Organic chemical contaminants, including bacteria, that may come from sewage treatment synthetic and volatile organic chemicals, that plants, septic systems, agricultural livestock are by-products of industrial processes and operations, and wildlife. petroleum production, and can also come Inorganic contaminants, such as salts and from gas stations, urban storm water runoff, metals, that can be naturally occurring or result agricultural application, and septic systems. from urban storm water runoff, industrial or Radioactive contaminants, which can be domestic wastewater discharges, oil and gas naturally occurring or the result of oil and gas production, mining, or farming. production, and mining activities. Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses.

In order to ensure water is safe to drink, the United States Environmental Protection Agency (EPA) and the State Water Resources Control Board (SWRCB) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. SWRCB regulations also establish limits for contaminants in bottled water to provide the same protection for public health.
